29 March 2019: Seminar by Dr Roland Knorr

Department of Physics, James Knott Room (PH132), 10am

Fluido-phagy: Intracellular wetting regulates autophagy of phase separated condensates and the cytosol

Dr Roland Knorr (Max Planck Institute of Colloids and Interfaces, Potsdam)

Phase separation generates functional, subcellular condensates with fluid-like properties. The mechanisms that degrade fluid phases in cells, however, are not fully understood. Clearance of condensates involves autophagy, a conserved pathway in which membrane sheets isolate portions of the cytosol to form autophagosomes, which then fuse with lysosomes for cargo breakdown. Here, we studied the assembly of autophagic membranes at fluid interfaces in both living and synthetic cells. A minimal physical model shows that interfacial tension determines whether isolation membranes will sequester the condensate entirely, or will prematurely close and degrade the condensate in a piece-meal fashion. In the latter case, curvature-inducing proteins confer a regulatory switch that associates isolation membranes with condensates, however, without degrading them. Thus, condensates persist and serve as a platform to assemble cytosol-degrading autophagosomes repeatedly. Our findings suggest that the autophagic breakdown of fluids—fluidophagy—is a wetting phenomenon, which is controlled by elasto-capillary feedback between the phase-separated condensate and the isolating membrane.

20 March 2019: Seminar by Dr Rhoda Hawkins

Department of Physics, Room PH30, 1pm

Modelling mechanics of the cell nucleus

Dr Rhoda Hawkins (University of Sheffield)

Experiments on migrating cells in microfluidic devices have shown that cancer cells are able to deform their nucleus and move through small constrictions more easily than non cancerous cells. The cell nucleus is more solid like than the rest of the cell. Whilst the cytoplasm deforms relatively easily, the nucleus shows more resistance to deformation and restricts the ability of migratory cells to pass through small constrictions. I will present theoretical work that we have done to model the nucleus and calculate the traction force field required to deform the nucleus so a cell can pass through a constriction. We have developed an algorithm to calculate the traction force field from experimental images of deforming nuclei. The results of our calculations depend on the details of the mechanical properties of the model nucleus. I will therefore discuss the mechanical properties of the nucleus and ways we could improve our model. Finally, I will discuss the active mechanisms by which cells may generate the necessary forces to deform the nucleus.

Carbon Nanotube-Based Lyotropic Liquid Crystal Microdroplets in Bulk and on Solid Surfaces

Dispersions of long, rod-like particles such as carbon nanotubes are known to form spindle-shaped, cylindrically symmetric elongated nematic liquid crystalline droplets in coexistence with the isotropic phase. Their shape and director field structure depends on the size of the drops, the interfacial tension, anchoring strength and elastic constants. In contact with a wall, the droplets become more elongated due to the effects of line tension. By visualising hundreds of nematic droplets of carbon nanotubes dissolved in chlorosulfonic acid and applying elasticity theory to fit the data, we extract information on the elastic and surface properties of the droplets. For sessile drops we find that the ratio of the line tension and the interfacial tension for this particular system equals −0.84 ± 0.06 μm. This ratio is 2 orders of magnitude larger than what has been reported for conventional fluids, in agreement with scaling arguments.

25 October 2017: One-Day Workshop on Droplet Coalescence

13-15 September 2017: Nanofluidics in Biological Systems Workshop

Durham University.

This Joint PoLNet2 & Durham BSI Workshop will bring together people from biological/physiological background and physicists/engineers to discuss challenges and opportunities, both in terms of the fundamental scientific questions, and strategies/methods to answer them. The workshop will focus on systems where unusual biophysics takes place, often beyond existing theories e.g. aquaporins, fluid dynamics at biointerfaces and biolubircation between rubbing membranes.

6-8th September 2017: External Event - 2nd Edwards Symposium. Challenges and Opportunities in Soft Matter

University of Cambridge.

Background: This series marks a fitting tribute to the life and work of Professor Sir Sam Edwards FRS, one of the great scientific minds of the 20th Century. Sir Sam played a pivotal role in bringing advances in the physical sciences to bear on major industrial problems. His fundamental contributions to soft matter theory ranged from polymer melts, through gels, colloids, granular materials and glasses through to optimisation problems.

13.30 Soft Matter: A Case for Self-Assembling Peptides, Dr Rudy Koopmans (abstract below)

14.00 Dr Sandra Hofmann

Abstract: Soft Matter: A Case for Self-Assembling Peptides, Dr Rudy Koopmans: Taking the long term view, materials of the future need to be conceived based on renewable natural principles. Peptides and proteins are functional oligomers and polymers par excellence demonstrating how their self-organisation capability enables the construction, from the bottom-up, of functional materials with unique performance characteristics. A few examples are presented.

Please register (by email to admin.bsi@durham.ac.uk) if you wish to attend.
